Engineers now construct 'forgiving' highways to protect errant motorists. For example, if you crash into an engineered roadside device your chances are ten times better than if the device was immovable. Forgiving highways combined with safer vehicles have reduced the fatalities in Canada from over 7000 in 1970 to less than 4000 in 1995. The next generation of highways will have to adress the major cause of road crashes; driver error. Such highways will be 'caring' highways and they will attempt to keep motorists away from harm rather than simply minimizing the harm. The research for this paper identifies the degree of caring and forgiveness required of a safe highway. The potentional solitions includes: selected Intelligent Transportation Systems such as, truck warning systems for rollover and runaway lanes, localized road weather information stations; technological enhancements such as, increased traction, more guidance, and pavement treatments; and behavior control at dangerous locations by speed photoradar and intersection red-light cameras.
